I fucked up today. My boss was talking to me, and I misinterpreted a tonal modulation and thought she was asking me a question when she was in fact giving me a compliment. So I answered with a rather apathetic affirmative acknowledgement (nodding head, half-hearted "mm-hmm" equivalent) when I should have answered with my trademark slightly embarrassed, brief-modest-lowering-of-eyes thank you.
